Description

Wide-area synchronous negative pressure adsorption device for bagged materials Technical Field The invention relates to the technical field of chemical packaging, in particular to a wide-area synchronous negative pressure adsorption device for bagged materials. Background Silica is an inorganic compound with a chemical formula of SiO 2 and widely exists in minerals such as quartz and sand in nature. In the industrial field, high purity silica is usually present in the form of white powder or granules and is often packaged in elongated flexible bags for use as a desiccant, filler or chemical raw material. Because the bag is soft in shape and easy to slide on the surface, high requirements are put on the uniformity, the synchronism and the flexibility of adsorption in the automatic carrying process so as to avoid wrinkling, breakage or falling of the bag. However, the following problems are often encountered with existing devices in use: (1) Traditional silicon dioxide in bags can cause material bags to be wrinkled or partially not grabbed when the upright post stacker crane clamps and carries because of the shape of the long strips, and can cause the material bags to be clamped and broken by clamping jaws when serious. (2) If the carrying end of the column stacker crane is changed into a sucker mode, the local suction force is too strong to damage the bag body due to too small stressed area of adsorption, or the whole suction force is insufficient to cause that materials fall off in carrying, so that a uniform and stable negative pressure field cannot be quickly established on a large-scale adsorption surface.
